The trick to doing good amateur work, is knowing when to get help from professionals.
Since the sites I am looking for have been totally consumed by fire, a long time ago, I would not expect to find obvious artifacts, but I can look at the chemistry of each possible site and see if that helps.
X-ray fluorescence semiquant multi-element analysis is a good way of seeing what something is made of, so I got the professional help of Spectra Chem Analytical to do this work for me.
Here are a few of the results, and they appear to support the ash idea, ( very strong support ) but a page of numbers by itself is not clear enough for most people for it to be "an ensample" as mentioned in 2nd Peter 2:6.
I think there is still something big to be found, something that is clear to everyone. Maybe while the ash was fluidised, many big items sank, much like the way the sulphur is part way down in the ash. Subsurface interface radar maybe worth a try.

this shows results for Dead sea water, sediments, and a dark layer at Gomorrah.and more results in excel format
Dark rock is from Sodom, dark layer is from Gomorrah, white porous rock is volcanic rock from New Zealand, and yellow deposit is carefully selected sulphur from a volcanic steam vent.
CONCLUSION: The results are consistent with these materials coming from precipitation in a drying out lake or sea. The source of these materials is unlikely to be an ancient city destroyed with fire and brimstone.
Unfortunately his conclusion based on one contaminated sample has convinced a few people, and that has resulted in a lack of interest from those who have the skill to check these sites properly.
